Explosion protection engineers at R. STAHL have developed an innovative air conditioning system specifically for use in hazardous areas. The ExSys Cool 8701 series ensures reliable air conditioning even in challenging conditions.

When working in hazardous areas, it is essential to maintain the right temperature for workers and machinery. Extreme temperatures, be it coldness, heat or high humidity, can lead to malfunctions and drastically reduce productivity. These conditions are especially critical in such environments and can pose Source: R. STAHLserious problems and hazards if adequate air conditioning is not provided.

The ExSys Cool 8701 air conditioning system was developed specifically for use in hazardous areas and is suitable for a wide range of applications, including control stations and cabinets (Ex e), shelters and overpressure-encapsulated cabinets (Ex p), analyzer rooms, workshop, control and drilling cabins, and containerized solutions for control panels and control technology.

R. STAHL's ExSys Cool 8701 series provides fully automatic cooling and ventilation around the clock. The system is certified as equipment according to strict ATEX and IECEx standards for use in Zone 1 and Zone 2, ensuring ultimate safety and efficiency. Its key features and benefits include:

• Constant temperature control: The temperature is automatically adjusted between +18° and +35° even in extreme conditions.
• Certification and safety: Fully certified for use in Ex e and Ex p enclosures, explosion-protected inside and outside.
• Easy installation: Plug-and-play design for straightforward installation without additional configuration.
• Flexibility: Available in preconfigured variants and as a customized solution.
• Self-supporting structure: Direct surface mounting is possible without additional support.
• Environmentally friendly: A refrigerant with a low global warming potential (GWP) is used.
• Global service: Comprehensive after-sales service from R. STAHL and partners.

The ExSys Cool 8701 uses thermal expansion valve technology to ensure constant and automatic cooling. With a cooling capacity of 4 kW to 6 kW according to EN 14511 L35 L35 and a wide ambient temperature range from -20° C to 50° C (optionally -40° C to 50° C or -20° C to 55° C), it meets the most demanding requirements for HVAC systems. The 4 kW system is delivered as a compact unit (1,245 mm x 600 mm x 778 mm) for plug-and-play wall mounting with IP 66 degree of protection. Other variants with a capacity of up to 6 kW will soon be available as a packaged model and in a split version.
